Abstract

Background: Little evidence exists on the diagnostic accuracy of clinical presentation in
distinguishing the type of herniation in patients with lumbar disc disease. This study was
undertaken to examine the correlation between clinical features and herniation type in lumbar disc
hernia.
Methods: One hundred and fifty consecutive candidates for lumbar discectomy were
examined. The initial assessments, including location and duration of pain, neurological
examination, and straight leg-raising (SLR) tests were performed by an independent observer who
was unaware of the final diagnosis. Intraoperatively, all patients were assessed by a single
neurosurgeon for the presence of disc protrusion or extrusion.
Results: Among 90 men and 60 women (mean age: 41.4, range: 18 – 75 year), 85 patients had
disc protrusion and 65 had extruded disc. Patients with radicular pain alone and those who
experienced a resolution of low back pain followed by an increased severity of radicular pain were
6.5 (P < 0.002) and 10.2 (P < 0.000) times more likely to have an extruded disc, respectively. The
mean preoperative duration among the group of patients with extruded disc (11 weeks) was
significantly shorter than the protruded ones (18.6 weeks) (P < 0.005). Among all subjects, 103
patients showed neurological abnormalities. There was no association between the presence of
neurological deficits and the type of herniation (P > 0.005). In patients with positive crossed
straight leg-raising (N = 43), 33 had extruded disc and 10 had protruded disc. The positive crossed
SLR test correlated significantly with the type of herniation (relative risk = 2.56, P < 0.000, and X2 =
27.4).
Conclusion: In the lumbar disc disease, there were three groups of patients: a) those with
radicular pain alone, b) those who experienced an increased severity of radicular pain followed by
resolution of back pain, and c) patients with positive crossed SLR test who had a high probability
of harboring an extruded disc. There was no significant association between the neurological
abnormalities and the type of herniation.
